Girls often face this problem when they approach all the responsibilities of contraception. By this time, they become less discharged, and the desire to have sex becomes stronger. What can be done in this situation? This is discussed in more detail in the article.

What is the menstrual cycle?
The female reproductive system is an integral system, and its function is procreation. It reaches maturity or optimal activity towards the end of puberty (16-18 years of age). At the age of 45-55 years, reproductive function, hormonal and menstrual regulation gradually disappear.
What follows from this? From the age of 16 until the onset of menopause, the female body is active and ready for conception, bending and breastfeeding. This readiness is supported by consistent research at all levels of the reproductive system and is demonstrated by the presence of menstruation and ovulation.
What is the menstrual cycle? The menstrual cycle is a series of monthly changes that prepare a woman”s body for the possibility of pregnancy. Ovulation occurs every month when an egg leaves the ovary to meet a sperm. If fertilization does not occur, the egg is destroyed and the woman begins to menstruate.
The cycle is counted from the first day of one menstruation to the first day of the next. On average, the cycle length is 21-35 days. With hormonal imbalances or chronic stress, the duration may increase or decrease.
In the classic version, the menstrual cycle is natural and monthly and includes ovulation and the “farm window”. Interruption of the cycle occurs only during pregnancy and in the first few months after childbirth. However, it happens that ovulation does not occur for a long time, months or up to a year.
Physiology of the menstrual cycle
Menstruation is the name for bloody discharge from the genitals that regularly occurs in women of childbearing age. These secretions include frozen endometrial cells, glandular secretions of the cervix, uterus and vagina, blood clotting enzymes and debris from destroyed eggs.
The normal menstrual cycle consists of two phases (follicular and luteal), in which ovulation (the release of mature eggs) occurs. The main hormone in the first phase of the cycle is follicle-stimulating hormone (FSH). It is produced in the pituitary gland and is responsible for the growth of follicles and the synthesis of estrogen in the ovary.
The follicle is the precursor of a mature egg. In one cycle, several follicles can mature simultaneously in the ovary. When their maximum reaches a size of 14 mm in diameter (becomes dominant), the maturation of the remaining cells stops. This process is a kind of natural selection, during which only strong and viable eggs remain.
At the end of the follicular phase, ovulation occurs. Fertilization is possible about a day after the egg enters the ovary.

Most girls with regular sex life are interested in the issue of pregnancy in the first days of menstruation. This article describes the features of women”s.
After the release of eggs, the luteal phase begins. Usually its duration is about 14 days. However, even for one woman, the cycle can fluctuate depending on the state of health.
The main hormone of the luteal phase is progesterone, which is produced in the ovaries by the “luteal body”. Progesterone prepares the endometrium and the entire female body for implantation of a fertilized egg. If conception does not occur, endometrial shedding begins after 14 days in the form of menstruation.
Favorable and unfavorable times for conception
The process of conception is possible within 48 hours after ovulation. At this time, the mature egg is active and is not destroyed. In the absence of fertilization, the egg dies 24-48 hours after ovulation.
Once the sperm enters the reproductive tract, the egg is fertilized. The lifespan of germ cells largely depends on the characteristics of a man’s physiology, the presence of chronic diseases, bad habits and the composition of sperm.
The maximum lifespan of sperm is 5-7 days. Thus, seven days plus two days after ovulation are “dangerous” from the point of view of conception. Pregnancy is possible from 7 to 16 days of the cycle.

Is pregnancy possible on the last day of menstruation?
To determine the exact time of ovulation, the “calendar” method is used. It is impossible to unambiguously determine the date of ovulation without additional research, which makes it very unreliable. Although the follicular phase has its own time frame, its duration is often variable. This means that ovulation can occur on the 7th day of the cycle.
The most reliable method for determining the duration of ovulation and conception is the study of cervical mucus. Conception is determined by the qualitative characteristics of mucus at different stages of the cycle.
- Day 5 — no mucus, no conception.
- Day 8 — no mucus, no pregnancy.
- Day 12 — A small amount of cloudy, sticky discharge, no pregnancy.
- Day 15 — Copious discharge of egg white mucus, the beginning of the “fertile window”.
- Day 28 — no mucus, no pregnancy.
Basal body temperature measurements also show this result. However, tracking the time of ovulation requires a longer time — 4-5 months. Measuring luteinizing hormone and estradiol levels can also predict the time of conception.
Considering that sperm live in the female reproductive tract for up to a week, the risk of conception on the last day of menstruation is very high. If a woman”s menstrual cycle is short, less than 28 days, her chances of conceiving are also higher.
Possible methods of contraception
If pregnancy is not desired, it is very important to use a reliable method of contraception on the last day of your period. If sperm enters the genital tract, it is recommended to take emergency contraceptive measures aimed at preventing egg implantation and some diagnostic measures (after at least two weeks).
- Pregnancy test. Test strips react to hCG levels in urine at a level of 10-15 MIU/ml.
- Blood test for hCG. The study should be carried out 8-10 days after the expected conception.
A woman should take care of contraception in advance, since the possibility of pregnancy on a critical day still exists. The best options: condoms, IUDs, COCs.
